General Procedures -- TWIST

Midas Web Interface | Electronic Log book

Dealingwith hardware problems

Most of the interaction is done at the machine midtwist in the M13 Counting Room's "Executive Class". The login at that machine is twistonl, with the usual TWIST password. You can also log into midtwist with the usual TWIST account name and password.

Most of these programs can be accessed from any terminal by logging into the appropriate machine. But be warned: Netscape seems to crash if you run it from two different terminals under the same login to the same machine!

Some simple instructions for various systems:

General

Basic general operating instructions are available. (Read these first.)

DAQ

MIDAS Status and control is done via the Midas web interface. See the basic general operating instructions.

More detailed DAQ instructions are available, including instructions on restarting DAQ and/or Slow Controls software, and handling some alarms.

To restart the e-log and history.

Reading the runlog, especially older entries.

Slow Controls and Monitoring

Some documentation in PostScript format:

• High Voltage Control: setting and checking HV levels.
• Restarting the Slow Controls: what to do when everything dies.

Online analysis and histogramming

Use Mofia to analyze the data, and Paw++ to look at the resulting histograms. There are three kinds of Mofia programs available:

• qod (for monitoring Quality of Data and watching for hardware problems)
• mofia (for analysis, particularly involving particle tracking)
• photo (for examining events one by one on the event display)

Miscellaneous

• Printing a window or screen region (from midtwist only)
• Getting a proper sound volume on the DAQ "man-in-the-box" messages.
• Basic general operating instructions
• Controlling M13 with EPICS
• Scaler rates as recorded in ODB
